SUPPLEMENTARY INFORMATION: 

Discussion 

On July 28, 2012, we received a report 

of a GEnx-1B engine failure installed on 

a Boeing 787 (B787) airplane. Boeing 

was conducting routine ground testing 

of the B787, before aircraft delivery. 

During a taxi test, one engine’s FMS 

fractured just aft of the coupling nut. 

The low-pressure turbine (LPT) rotor 

shifted axially backwards, resulting in 

LPT blade and vane clashing. The LPT 

case contained the failure and debris 

was released out the tailpipe. There was 

no engine overspeed as the LPT rotor 

remained coupled to the fan rotor at the 

FMS spline. On August 14, 2012, we 

received a second report concerning the 

GEnx engine, this time about an FMS, 

installed in a GEnx-1B engine, that was 

found cracked during an on-wing UI. 

This condition, if not corrected, could 

result in failure of the FMS resulting in 

one or more engine failure(s) and 

possible loss of the airplane. 

Relevant Service Information 

We reviewed GE Service Bulletin (SB) 

No. GEnx-1B S/B 72–0107, Revision 2, 

dated September 14, 2012, and SB No. 

GEnx-2B S/B 72–0091, Revision 1, dated 

September 14, 2012. The SBs describe 

procedures for performing UI 

inspections of FMS P/N 2331M20G02, 

P/N 2332M81G01, and P/N 

2332M33G01. 

FAA’s Determination 

We are issuing this AD because we 

evaluated all the relevant information 

and determined the unsafe condition 

described previously is likely to exist or 

develop in other products of the same 

type design. 

AD Requirements 

This AD requires accomplishing the 

actions specified in the service 

information described previously, 

except as discussed under ‘‘Differences 

Between the AD and the Service 

Information.’’ 

Differences Between the AD and the 

Service Information 

The SBs require an initial FMS 

inspection within 30 days of the SB 

date. This AD requires an initial FMS 

inspection before further flight. 

Interim Action 

We consider this AD interim action. 

Root cause is still under investigation, 

but the failure of the FMS is likely due 

to environmentally assisted cracking; a 

type of corrosive cracking that is timedependent. 

FAA’s Justification and Determination 

of the Effective Date 

An unsafe condition exists that 

requires the immediate adoption of this 

AD. The FAA has found that the risk to 

the flying public justifies waiving notice 

and comment prior to adoption of this 

rule based on the reported engine 

failure, the crack find, and that the root 


pmangrum on DSK3VPTVN1PROD with RULES
58472 Federal Register / Vol. 77, No. 184 / Friday, September 21, 2012 / Rules and Regulations 

cause is still somewhat unknown. We 

therefore determined that a repetitive 

inspection interval needed to be 

established. The repetitive inspection 

interval is less than the time it would 

take to process a proposed AD. 

Therefore, we find that notice and 

opportunity for prior public comment 

are impracticable and that good cause 

exists for making this amendment 

effective in less than 30 days. 

Comments Invited 

This AD is a final rule that involves 

requirements affecting flight safety and 

was not preceded by notice and an 

opportunity for public comment. 

However, we invite you to send any 

written data, views, or arguments about 

this AD. Send your comments to an 

address listed under the ADDRESSES

section. Include the docket number 

FAA–2012–1017 and Directorate 

Identifier 2012–NE–30–AD at the 

beginning of your comments. We 

specifically invite comments on the 

overall regulatory, economic, 

environmental, and energy aspects of 

this AD. We will consider all comments 

received by the closing date and may 

amend this AD because of those 

comments. 

We will post all comments we 

receive, without change, to http:// 

www.regulations.gov, including any 

personal information you provide. We 

will also post a report summarizing each 

substantive verbal contact we receive 

about this AD. 

Costs of Compliance 

We estimate that this AD will affect 

11 GE GEnx turbofan engines installed 

on airplanes of U.S. registry. We also 

estimate that it will take about 9 workhours per engine to perform the UI of 

the FMS, and that the average labor rate 

is $85 per work-hour. The estimated 

cost of one set of inspection tooling is 

$105,000. Based on these figures, we 

estimate the total cost of this AD to U.S. 

operators to be $113,415. 

Authority for This Rulemaking 

Title 49 of the United States Code 

specifies the FAA’s authority to issue 

rules on aviation safety. Subtitle I, 

section 106, describes the authority of 

the FAA Administrator. ‘‘Subtitle VII: 

Aviation Programs’’ describes in more 

detail the scope of the Agency’s 

authority. 

We are issuing this rulemaking under 

the authority described in Subtitle VII, 

Part A, Subpart III, Section 44701: 

‘‘General requirements.’’ Under that 

section, Congress charges the FAA with 

promoting safe flight of civil aircraft in 

air commerce by prescribing regulations 

for practices, methods, and procedures 

the Administrator finds necessary for 

safety in air commerce. This regulation 

is within the scope of that authority 

because it addresses an unsafe condition 

that is likely to exist or develop on 

products identified in this rulemaking 

action. 

Regulatory Findings 

This AD will not have federalism 

implications under Executive Order 

13132. This AD will not have a 

substantial direct effect on the States, on 

the relationship between the national 

government and the States, or on the 

distribution of power and 

responsibilities among the various 

levels of government. 

For the reasons discussed above, I 

certify that this AD: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Is not a ‘‘significant rule’’ under 

DOT Regulatory Policies and Procedures 

(44 FR 11034, February 26, 1979), 

(3) Will not affect intrastate aviation 

in Alaska, and 

(4) Will not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act.

SUPPLEMENTARY INFORMATION: 

I. Background 

The Indian Gaming Regulatory Act 

(IGRA or Act), Public Law 100–497, 25 

U.S.C. 2701 et seq., was signed into law 

on October 17, 1988. The Act 

establishes the NIGC and sets out a 

comprehensive framework for the 

regulation of gaming on Indian lands. 

On October 8, 2008, the NIGC published 

a final rule in the Federal Register 

called Technical Standards for 

Electronic, Computer, or Other 

Technologic Aids Used in the Play of 

Class II Games. 73 FR 60508. The rule 

added a new part to the Commission’s 

regulations establishing a process for 

ensuring the integrity of electronic Class 

II games and aids. The standards were 

designed to assist tribal gaming 

regulatory authorities and operators 

with ensuring the integrity and security 

of Class II gaming, the accountability of 

Class II gaming revenue, and provide 

guidance to equipment manufacturers 

and distributors of Class II gaming 

systems. The standards do not classify 

which games are Class II and which 

games are Class III. 

On November 18, 2010, the NIGC 

issued a Notice of Inquiry and Notice of 

Consultation advising the public that 

the NIGC endeavored to conduct a 

comprehensive review of its regulations 

and requesting public comment on 

which were most in need of revision, in 

what order the Commission should 

review its regulations, and the process 

NIGC should utilize to make revisions. 

75 FR 70680. On April 4, 2011, after 

consulting with tribes and reviewing all 

comments, the NIGC published a Notice 

of Regulatory Review Schedule (NRR) 

setting out a consultation schedule and 

process for review. 76 FR 18457. Part 

547 was included in the third regulatory 

group reviewed pursuant to the NRR. 

II. Previous Rulemaking Activity 

On July 8, 2011, the Commission 

began a series of tribal consultations on 

part 547. Based in part on the 

recommendations to the Commission 

during consultations, on August 10, 

2011, the Commission requested tribes 

nominate tribal representatives to serve 

on a Tribal Advisory Committee (TAC) 

to assist the Commission in drafting 

changes to part 543 and these technical 

standards. Beginning on October 20, 

2011, the TAC held four meetings in 

which the Commission participated. All 

of the meetings were open to the public 

and three of the four were transcribed. 

On January 12, 2011, as a result of those 

meetings, the TAC submitted a 

proposed part 547 regulation to the 

Commission. 

Upon reviewing the TAC’s 

recommendation, and taking into 

consideration comments received 

through tribal consultations, the 

Commission published a discussion 

draft of the amended technical 

standards on its Web site. The 

discussion draft adopted a number of 

the TAC’s recommendations, such as 

moving requirements that more 

appropriately belong to the Minimum 

Internal Control Standards found at 25 

CFR part 543. 

After publishing the discussion draft, 

the Commission conducted 

consultations in Mayetta, KS and San 

Diego, CA. In addition to tribal 

consultations, the Commission 

requested public comment on the 

discussion draft. Considering the 

comments received in response to the 

discussion draft, the Commission 

published a Notice of Proposed 

Rulemaking (‘‘NPRM’’) on June 1, 2012. 

77 FR 32465. The NPRM invited 

interested parties to participate in the 

rulemaking process by submitting 

comments and any supporting data to 

the NIGC by July 31, 2012. After 

receiving several requests to extend the 

comment period, the Commission 

published notification in the Federal 

Register that it would do so by two 

weeks, establishing a new comment 

deadline of August 15, 2012. 77 FR 

43196. 

In addition to soliciting public 

comment in the Federal Register, the 

Commission also conducted an 

additional five tribal consultations to 

discuss the proposed rule with 

interested tribes and industry 

representatives. As with the discussion 

draft, the consultations and written 

comments have proven invaluable to the 

Commission in making needed 

amendments to the Class II technical 

standards.
